You couldn't prove a single thing and yet you call me a troll. You keep blabbering the same thing when youyou are actually arguing "It existed at that time" Was observed at that time? Was it founded and then established as scientific phenomenon at that time? No, it was never and yet you claim that it was like that. You argument has a major logical flaw. And you claim the fact that you didn't reply with a irrelevant argument and call me a troll. What about you correcting my mistakes and missing the point of the comment? And you are asking "What are you trying to say?" You act like you don't know what you did but in reality you know exactly what you did wrong. And tell that my comments have no points while nearly 95% of your comment are missing the point or correcting my mistakes and call me a troll? And when you are actually arguing over this you muster the same point again and again. I have to explain it again and again.
